Broach base bore in cylinder head

(Repair stage)

Decarbonize and clean cylinder head perfectly, particularly the inside of the valve seat inserts. Select correct guide sleeve (2) and remove swarf from the cutters of the broach (1) with a stiff plastic brush or the like.

Note

The broach cutters must be cleaned before each broaching operating.

Provide guide sleeve, basic bore and complete broach with ample supplies of paraffin.

0285 - Checking and replacement of the valve guides Engines 601, 602 (except 602.98), 603

Insert broach into the guide sleeve so that when the guide sleeve rests on the valve seat insert (3) the first cutter of the broach is located in the base bore. In so doing note that the correct side of the guide sleeve is put on the valve seat.

Centre guide sleeve by rotary movements in the valve seat insert.

Note
Drive the broach briskly through with an aluminium mandrel, approx. 130 mm long, and a plastic hammer of approx. 250 g.

Note
The high spot (arrow) on the intake valve seat inserts is to be removed before inserting the guide sleeve.

Inserting valve guide

Drive home valve guides with punch and hammer, when the valve guides are not supercooled and the cylinder head is not heated up. Coat valve guides with tallow or oil before driving home.
